The AndroidartsWB icons-set was never released as an usable AmigaWB archive (.LHA archive containing .INFO icons), but I've got the preview images from the website to convert them as real Amiga WB .info icons. Missing alot of system icons, but they are looking good. Anyway, in my opinion, the author just mades some mistakes with the icons size and the palette pens order, I suppose he's missing workbench experiences. i.e.: pens indice for DefWB/Iconographics compatibility are in the wrong positions. I fixed them just for fun, but I can't release any archive without any permission.

This is, in my opinion, the right corresponding palette indice for an icons-set compatible with WB3Def/Iconographics:
